On its own this seems a fairly low-impact problem: only DSpace Administrators can set LDN template names in services, and you typically need more access to manipulate files on the server. However, this vulnerability was included as part of an attack chain that demonstrated the ability of a DSpace Administrator to put the malicious Velocity payload in a predictable place (e.g. temporary log file from a running process) and then …
A remote OAI endpoint configured as a harvest source for a DSpace collection can supply malicious ORE XML that results in a local file from the DSpace server being ingested as a bitstream. Only Collection, Community and Site Administrators can configure a collection for OAI harvest, however an attacker may use stolen credentials to escalate into local file/data disclosure, or a compromised OAI endpoint could also supply malicious XML.
When chained with the LDN Path Traversal Attack identified in GHSA-9qm4-rh6w-pq5x, it may be possible to execute Java directly from Velocity templates using reflection. This is a very high impact vulnerability, but the attack can only be performed by a user that has DSpace Administrator privileges. Disabling LDN (see below) removes all known attack paths. Velocity is also used for email templating, but there is no known attack path via …
The ability to overwrite a file in /dspace/config or /dspace/bin is not desired, and could result in a denial of service attack. To actually use the curation reporter to perform an attack that escalates privileges, either a custom curation task would be needed (these can only be deployed by a system administrator), or the output would have to contain some executable information that is combined with other attacks, as a …
Two related XXE injection possibilities have been discovered, impacting all versions of DSpace prior to 7.6.4, 8.2 and 9.1. External entities are not disabled when parsing XML files during import of an archive (in Simple Archive Format), either from command-line (./dspace import command) or from the "Batch Import (Zip)" user interface feature. (Likely impacts all versions of DSpace 1.x <= 7.6.3, 8.0 <= 8.1, and 9.0) External entities are also …
A path traversal vulnerability is possible during the import of an archive (in Simple Archive Format), either from command-line (./dspace import command) or from the "Batch Import (Zip)" user interface feature. This vulnerability likely impacts all versions of DSpace 1.x <= 7.6.3, 8.0 <= 8.1, and 9.0. An attacker may craft a malicious Simple Archive Format (SAF) package where the contents file references any system files (using relative traversal sequences) …
DSpace open source software is a repository application which provides durable access to digital resources. In affected versions the ItemImportServiceImpl is vulnerable to a path traversal vulnerability. This means a malicious SAF (simple archive format) package could cause a file/directory to be created anywhere the Tomcat/DSpace user can write to on the server. However, this path traversal vulnerability is only possible by a user with special privileges (either Administrators or …
DSpace is an open source turnkey repository application. In version 7.0, any community or collection administrator can escalate their permission up to become system administrator. This vulnerability only exists in 7.0 and does not impact 6.x or below. This issue is patched in version 7.1. As a workaround, users of 7.0 may temporarily disable the ability for community or collection administrators to manage permissions or workflows settings.
